Abstract
Western studies showed vascular caliber changes post-endovascular aneurysm repair (EVAR). This study aims to evaluate for postoperative changes of the common femoral artery inner diameter (CFA ID) in the Asian population. From January 2011 to June 2016, 202 patients who underwent EVAR were reviewed. CFA IDs were evaluated at 3 fixed levels on computed tomography (CT) aortograms. Preoperative and postoperative measurements were compared. Per-groin analysis was carried out after division into percutaneous access endovascular aneurysm repair (PEVAR) and surgical access endovascular aneurysm repair (SEVAR) groups. Independent sample t-test compared for differences in overall CFA ID changes between PEVAR andSEVAR groups. Paired sample t-test evaluated CFA ID changes in each group. P value < 0.05 was considered significant. One hundred and twenty patients were included, with 200 groins subsequently analyzed. The PEVAR and SEVAR groups have no significant demographic differences, except in sheath size and duration of CT aortogram follow-up. No significant differences in overall CFA ID changes comparing PEVAR and SEVAR groups (-0.12±1.05mm, -0.10±0.81mm, P=0.36). No significant overall CFA ID changes in both PEVAR (7.92±1.23mm, 7.80±1.38mm, P=0.34) and SEVAR groups (7.47±1.44mm, 7.36±1.64mm, P=0.15). No significant differences in CFA caliber changes comparing PEVAR and SEVAR. No significant CFA caliber changes in either group.
